Pengaruh Salinitas terhadap Perkembangan Parasit pada Benih Gurami, Osphronemus goramy
Abstract: Research was
conducted to know the effect of salinity on the reduction of parasites in
Gouramy (Osphronemus goramy). The Research was performed using completely
Randomized design with 5 salinity treatments (water pond, water with salt
concentration 0, 2, 4 dan 6 g/L) with 4 replications. The 5-7 cm of gouramy
fingerling were reared as on treatments and the parasites were counted using skin scrapping dan wet mount methods.
Observation was performed every 3 day for 15 days on parasite intensity,
prevalence, mortality, symptoms and water quality.
The result showed that several parasites including Trichodina sp.,
Apiosoma sp., Ichthyophthirius sp., Oodinium sp., dan Henneguya sp were
observed. The highest intensity and prevalence was found in Trichodina sp. The
Salinity and lenght administration were significantly decrease number
parasites. Salinity treatments (2, 4 dan
6 g/L ) for 3 days could totally removing Trichodina sp. from fishes. Meanwhile
the data of other parasite species were unsignificant due to the low level of
its intensity and prevalence. Salinity administration in level 6 g/L could
reduce mortality.
